- TRANSOM-OPERATING MECHANISM.

I Specification of Letters Patent.

Application filedOctober 14, 1918. Serial No. 257,951.

To all whom it may concern v I Be it known that I, CLARENCE VICTORJONES, a citizen ofthe United States of America,and resident of 230,Yonge street, city'of Toronto, county of York, Province of Ontario, inthe Dominion of Canada, have invented certain new and usefulImprovements in Transom-Operating Mechanism, of which the-following is aspecification.

The invention relates to improvements in transom operating mechanism asdescribed in the presentxspecification and illustrated in theaccompanyingdrawings that form a part of the same. Y Y

The invention consists essentially of the novel means employed forcontrollingthe movement of a transom against pressure adapted to-holdsame normally to an open position. y

The objects of the invention are to eliminate annoyance andinconveniencein adjusting transoms located out of "reach of theoperator, to p-rovidea means for guidingthe operatingchain in itsmovement thereby facilitating the adjusting of the transom and generallyto provide an operating mechanism for transoms and the like which willbe neat and pleasing in appearance, inexpensive to manufacture, simpleto operate, durable and efficient.

In the drawings Figure 1 is a perspective view of a transom held to anopen position by means of the present invention.

Fig. 2 is a diagrammatic view in vertical section through the guidingmechanism for the operatingchain and the catch for said chain.

Fig. 3 is a vertical sectional view through a closed transom and frameand taken substantially on the line AA of Fig.1.

Fig. 4 is a front view of the housing for the chain guiding rollers withsaid rollers shown in dotted lines.

Fig. 5 is a detail of one of the spring hinges employed to hold thetransom normally to an open position.

Fig. 6' is a detail of the catch employed to hold the operating chain toanydesired position.

Like numerals indicate corresponding parts in the various figures.

Referring to the drawings the transom 1 is provided with one or morereverse hinges 2 secured to the outer side thereof and to the frame 3and adapted to exert pressure to hold said transom normally to an openposition (the construction of said hinge being more fully described andclaimed in another application) 4 is a bracket secured to the inner.side of the sash and having its end turned out- Patented Mar. 18, 1919.

wardly at right angles and projecting 1 slightly past the edge of theframe 5.

The mowement of the transom is controlledby means of a chain 6 securedat one end to the bracket 4 and operating through a guiding devicemounted onthe frame 5 substantlally opposite the bracket 4 and through acatch .7located below said guiding device. The housing for the chainguiding spools conslsts of a substantially rectangular box 8 adapted tobe countersunk in the frame 5,

vexed considerably forming an enlarged lower portion 11 and then beingturned inwardly at right angles and slotted as at 12 and projectingoutwardly in a flange 13, said flanges 10 and 13 being provided withsuitable openings to accommodate screws 14 for securing the housing tosaid frame 5.

The top 9 is provided with a chain slot 15 located directly behind theouter end of the bracket 4 when the transom is in its closed position.

16 and 17 are the chain guiding spools rotatably mounted on shafts 18transversely arranged in the housing 8, the spool 16 being positioned inthe upper portion of said housing and the spool 17 being positioned inthe enlarged portion 11 and considerably in advance of said spool 16,said spools being spaced from one another substantially the thickness ofthe chain 6.

The chain 6 is secured at its upper end to the bracket 4 and extendsthrough the slot 15, around the rear of the spool 16, over the front ofthe spool 17 and out through the opening 12 from where it extendsdownwardly through the opening in the upper end of the catch 7 and intothe slot 18 in the front wall of said catch where it is held against thepressure of the spring hinges 2.

In the operation of the invention when it is desired to open the transomit is simply necessary to pull outwardly on the lower end of the chain 6and immediately upon the disengagement of said chain from the slot 18the hinges 2 will force the transom open, the chain in the meantimetraveling freely over the spools 16 and 17. When the transom has openedthe required distance the chain is simply pushed back into the slot 18thus preventing further outward movement of the transom. To close thetransom the chain is simply disengaged from its slot and pulleddownwardly and again placed in its slot. 7

The employment of the chain guiding spools located in their housing in adirect line with the chain catch and directly behind the bracket fromthe transom provides for a straight pull on the transom thus giving afreedom of movement which is not obtained with the employment of thedevices heretofore known.

What I claim is 1. In transom operating mechanism, in combination, atransom provided with a bracket having its end projecting over the framethereof, guide mechanism mounted in said frame adjacent to said bracket,said guide mechanism consisting of a pair of spools positioned one abovethe other, the uppermost of said spools being countersunk in said frameand the lowermost spool being adapted to project a considerable distancebeyond the face of said frame, a chain secured to said bracket andoperating over said spools, a housing for said guide mechanism and acatch mounted on said frame below said guide mechanism for locking saidchain.

2. In transom operating mechanism, in combination, a transom adapted tobe spring held normally to an open position, a bracket secured to saidtransom and having its end projecting over the frame thereof, chainguide mechanism mounted in said frame adjacent to said bracket andconsisting of a substantially rectangular housing counter sunk in saidframe and having the lower portion of its face conveXed andprojectingoutwardly from the face of said frame and slotted, a pair ofspools transversely mounted within said housing, one above the other,the lowermost of said spools being located within said convexed portion,a chain secured to said bracket and projecting through an openingthrough theface of said housing and extending over the rear of the upperof said spools, around the front f the lowermost of said spools andemerging through said slot and a catch for locking said chain.

Signed at the city of'Toronto, Ont, this 9th day of August, 1918.
